CLOSURE FOB GONTAIN'ING VEBSELS.

Specification of Letters Patent.

Patented March 17, 1908.

Application filed October 9, 1907. Serial No. 396,531.

To all whom it may concern:

Be it known that I, EUGENE D. CHELLIs, a citizen of the United States, residing at Portland, county of Cumberland, State of Maine, have invented certain new and useful Improvements in Closures for Containing Vessels, of which the following is a specification.

This invention relates to closures for vessels and more particularly to a bottle cap 10 havin a swinging cover which is to be held in a c osed position tightly upon the bottle and yet which will be readily openable for ac- In this type of bottle cap it has been difficult to secure a means for. lockin the cover which would hold tight on or inary stock bottles which vary slightly in size and form.

My present invention has for its object the rovision of a bottle cap which will be firmly eld in osition when closed and which may be readify opened by slight pressure properly applied.

My invention will be more fully described in the specification which follows and is illus-v trated in the drawings which form a part thereof. in which drawings:

Figure 1 is a front view of my cap in closed position, Fig. 2 is a side sectional view on the line 2 --2 of Fig. 1. Fig. 3- a transverse section on the line 33 Fig. 1. looking from below, and, Fig. l is an enlarged sectional detail of the locking li and interengaging men'ibers.

1 is a butt e neck. .2 a shoulder formed about the mouth of the bottle.

7 is a cap plate provided with lingers 15 which are adapted to engage the shoulder 2. These lingers are preferably arranged on the rear of the cap and depend from a rim 8 formed on the cap plate T.

18 is a cover pivoted to the cap plate at 19.

22 is a projection raised on the surface of the plate 7 and preferably located on theopposite side from the pivot 19.

21 is a corresptmding recess depressed into the under side of the cover 18 and adapted to receive the projection 14 is a spring lip preferably formed with a curved or bent portion 14 which gives to its point 14" a considerable degree of resiliency in its engagement with the shoulder 2 of the bottle.

14 is a projectin flap or car formed on the locking lip 14 and bent back towards the cover 18 to partially close the sides of the bent .portion 14 and afford a bearing surface for the thumb or thumb nail in o ening the cover so that the member will not e brought against the edge of the lockin lip.

4 is an opening which may e of any de scription according to the nature of the contents which the bottle is adapted to receive;

The cap is applied to the bottle in the usual manner of applying any ca s. Thisis accomplished by swinging 0 en t 0 cover 18 and applying the cap 7 fitte with a suitable washer to the mouth of the bottle by sliding it upon the same in such a manner that the fingers 15 will engage with the shoulder 2. After the cap is slid onto the bottle the rim 8 will snap down over the edge of the shoulder '2 so as to hold the cap 7 quite firml in position on the mouth of the bottle. he cover 18 is then swung to until the locking lip 14 is brought opposite to the pivot 19, which position the depression 21 in the lower side of the-cap 18 will be sprung down over the protion 14 of the locking lip 14. It will, therefore, be seen that the locking lip 14 will not only serve to hold the entire cap tight upon the mouth of the bottle but will also hold the cover 18 firmly against the plate 7 making of the cap a tight and perfect seal.

Various modifications may obviously be made in the form of the locking lip as well as in the fastening device.

1 What I therefore claim and desire to secure by Letters Patent is 1. A laterally swinging (over for a conlip, said lip having an inwardly turned side flange on its bent portion.

2. In a closure for :1 containing vessel hav-- ing a shoulder about its mouth, a laterally movable cover and a spring locking lip on said cover comprising an arched section terminating in a shoulder engaging lip.

3. A closure for a containing vessel having a shoulder about its mouth, a laterally movable cover and a spring locking lip on i said cover having an arched section terminating in a shoulder el'igaging lip and a segjection 22 by the action of the resilient pertaining vessel having a bent vessel engaging mental guard on the side of the lip arch to cover the edge of the seme 4. A laterally swinging cover for a 001k" mining vessel xaving a shoulder about its 5 mouth, and a spring locking lip thereon com.- prising an arched section terminating in shoulder engaging lip.
